(hrw8c10p78) Two uniform solid spheres have the same mass, 1.65 kg, but one has a radius of 0.206 m while the other has a radius of 0.804 m. For each of the spheres, find the torque required to bring the sphere from rest to an angular velocity of 367 rad/s in 14.5 s. Each sphere rotates about an axis through its center. Torque on sphere with the smaller radius.

You have been hired to design a spring-launched roller coaster thatwill carry two passengers per car. the car goes up a 10-m highhill, then descends 15m to the track's lowest point. you'vedetermined that the spring can be compressed a maximum o 2.0m andthat a loaded car will have a maximum mass of 400kg. for safetyreasons, the spring constant should be 10% larger than the minimumneeded for the car to just make it over the top. a) what spring constant (k) should you specify ? b) what is the maximum speed of a 350 kg car if the spring iscompressed the full amount.
